A low pressure system entered the central Plains on Friday (12/10), quickly strengthened, then turned northeast into the Great Lakes Friday night. An initial band of snow moved into northeast Wisconsin Friday afternoon, however the main band of precipitation impacted the region Friday night into Saturday morning (12/11).

Gulf moisture was in place (250 percent of normal) before the storm arrived. Strong forcing, coupled with strong mid-level frontogenetical forcing, steep mid-level lapse rates and a coupled jet structure led to snow accumulations that ranged from 8 to 13 inches over northern WI to under an inch over Kewaunee and Manitowoc Counties. East-central WI saw a wintry mix Friday evening turn to rain Friday night before changing to snow Saturday morning.

Hazardous road conditions were reported across the area, along with some power outages, especially across northern and northeast Wisconsin.
